What shall we learn from social networks whilst keeping Wikipedia unique ? being a team?

I discussed this with some German editors somewhere, probably at Wikimania. They have a more compact geography and many editors will phone each other when things get stressful. I'm involved in some of our London events and I think that they bring together editors who might not collaborate online but can share experiences offline. Of course it is then important to avoid that becoming a clique or a cabal. But I think that real life events can enthuse and remotivate people, especially collaborations such as the backstage pass events we have had at the British Museum.
